EARL Gr. VAIROUS, OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. l759,050, dated May 3, 1904.

Application filed July 21, 1902` Serial No. 116,457, (No model.)

Be it known that l', EARL Gr. lVATRoUs, la citizen et the United States, residing at Chicago, 1n the county oil Cook and State of lllinois, have invented a certain new and useful improvement in a Combined Fitting tor Soil- Pipes and Revent-ilipes, of which the following is a description, reference being had to the accompanying drawings, forming part olE this speciiication.

l\fly invention has for its object the provision otl a fitting of this character in which the litting for the soil-lyiipe and the fitting for the revent-jiipe shall be 'termed of a single casting, in which each iittingshall Jform a straight and unbroken continuation of the vertical pipe el which it is adapted to form a part, in which etlicient provision against siphoning of connected lixtures is made, and in which simplicity, compactness, and economy of construction are attained in a maximum degree.

ln the accolnpan ying drawings, Figure lis an elevation oi" a stack of soil and revent pipes equipped with my improved iittings, the sections ot' the pipes intermediate the fixtures being broken away to lessen the length ot the View; `liig. 2, a detail elevation of a single lixture disconnected Afrom the stack el pipes; Fig. S3, a middle vertical section ot' the iitting shown in Fig. 2; Fig. 4t, a cross-section oiE the same on the line l io't' Figs. l and 3, and Fig. 5 a cross-section on the line 5 5 thereof.

lhe same letters oit' reference are used to indicate corresponding parts Ain the several views.

As illustrated in the drawings, my combined litting comprises two parallel tubular sections A li, cast integral with each other and adapted to be interposed direetlyin a vertical stack ot' soil and revent pipes A H, the section A oit' the ittingtlnis constituting a portion of the vertical soil-pipe and the section B aportion of the vertical revent-pipe. At their upperends the two sections otl my improved iitting are provided with the usual hubs rf, 7) to receive the lower ends of the pipe-sections immediately above them, while their lower ends a /1 are adapted to lit into similar hubs upon the upper ends oi' the pipe-sections immediately beneath them, as usual.

At a point below its middle the section A ot' the iitting is enlarged to term within it a chamber (l o'lE greater size than the regular bore of the litting, and from the lower portion of this enlargement of the section projects the hub D, by which the pipe leading to the adjacent fixture is connected to the litting, such pipe thus discharginginto the lower portion of the enlarged chamber C. There is also 'formed within the litting-casting in the space between the upper portions ot' the tubular sections A and B a vertical chamber E, which constitutes a lateral extension ot' the tubular bore ot' the section A, and this chamber is connected at its upper end with therevent-section B oi' the fitting by the openingI F, this opening when the litting is assembled in a stack ot' pipe beinglocated above the water level of the adjacent tixture.

rlhe enlarged chamber C of the soil-pipe section of the iitting provides an air-space around the vertical bore ot' said section at the between the revent-pipe and the point ot' conl nection oi the [ixture with the soil-pipe section oi the fitting largely tend to prevent siphoning ot the fixture even in theabsence of the enlarged chamber (1; but the latter increases the eliectiveness of the chamber E in preventing' such siphoning.

rlhe formation oil the iitting in a single casting with straight soil-pipe and reventpipe sections parallel with each other and adapted to" be interposed, directly in the soil and revent pipes and torni continuations thereotl reduces to a minimum the number oi? connections to be made and joints to be calked and siinpliiies and cheapens the construction, as well as increasing .its compactness as compared with littings now commonly IOO in use, while the provision of the vertical chamber E between the ventpipe and the soil-pipe and opening throughout its length into the latter requires the employment of only two cores in casting the iitting as compared with the necessary employment of three cores in casting fittings, wherein the vertical chamber between the two pipes is separated from the soil-pipe throughout its length and simply opens into said pipe at its lower end.

The revent-sections of the fittings may of course be provided with the usual hubs c for the connection of vent-pipes of xtures, a single one of such hubs being shown in dotted lines on the lower tting in Fig. l, and the hubs D of the soil-pipe sections of the iittings may be located upon either side of the section or upon both sides, as usual.

Having thus fully described my invention, I claim# l. A combined iitting for soil-pipes and revent-pipes, comprising two parallel tubular sections cast integral with each other and adapted to be interposed directly in the 'soilpipe and revent-pipe and form vertical portions thereof, the interiors of the two sections of the fitting being directly connected with each other by an opening near their upper ends, and the soil-pipe section of the fitting being provided below said opening with a connecting-hub for the adjacent fixture; substantially as described.

2. A combined fitting for soil-pipes and re- Vent-pipes, comprising two parallel tubular sections cast integ'ral with each other and adapted to be interposed directly in the soilpipe and revent-pipe and form a part thereof,

the interiors of the two sections being directly connected with cach other by an opening near their upper ends and the soil-pipe section of the fitting being provided below said opening with an enlarged chamber and with a hub connection for the adjacent fixture opening into said chamber; substantially as described.

3. A combined fixture for soil-pipes and revent-pipes, comprising two tubular sections cast integral with each other and adapted to be interposeddirectlyin the soil and revent pipes and form a part thereof and having a vertical chamber connected at its upper end With the revent-pipe and in free communication With the soil-pipe throughout its length, and the soil-pipe section of the fitting having a hub connection for the adjacent fixture opening into said section at the lower end of said vertical chamber; substantially as described.

4. A combined fixture for soil-pipes and revent-pipes comprising two parallel tubular sections cast integral with each other and adapted to be interposed directly in the soil and revent pipes and form part thereof, the interiors of the two sections being directly connected with each other near their upper ends by an opening and the soil-pipe section of the fitting being provided with an enlarged chamber below said opening' and with a vertical chamber connecting said enlarged chamber with said opening and having a hub connection for the adjacent fixture opening into said enlarged chamber; substantially as described.,
